In this How To we are going to build less 451 with our GCC/G++ 4.8.2 cross-compiler. Be sure to start this build in a new terminal/tab to avoid any pollution from previous builds. This came about due to BusyBox's limited functionality with its less "applet", specifically this command: less -isM. If you are using BusyBox and its less applet you'll need to disable before being able to use the _real_ less program. You do that during compile time in the config menu.

Here is a list of source packages that we'll need for the build. You can either download them now or wait 'til later in the How To.
I recommend creating a workspace under your /home/<your user>/ directory that is dedicated to this build. So let's fire up your terminal and run the following:
NOTE: Depending on whether you are using a cross-compiler built from my other wikis you might need to change INSTALLDIR to point to your cross-compiler.
Build less
$ cd ../build/
$ ../src/less-451/./configure --prefix=/home/<your user>/workbench/less/final --host=$TARGETMACH CPPFLAGS=-I/home/<your user>/workbench/ncurses/final/include LDFLAGS=-L/home/<your user>/workbench/ncurses/final/lib
$ make
$ make install
Output
cd into the final directory and output its contents:
$ cd ../final/
$ ls
You should have the following directories:
bin
share
Make sure the binaries are for ARM:
$ cd bin/
$ file less
bash: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped
If you see something similar to above you're good to go ;-)
Lastly, move the contents of these directories, or the directories themselves if they do not already exist, to your custom Linux file system or dev board.
How To Build GNU less for ARM
Intro
In this How To we are going to build less 451 with our GCC/G++ 4.8.2 cross-compiler. Be sure to start this build in a new terminal/tab to avoid any pollution from previous builds. This came about due to BusyBox's limited functionality with its less "applet", specifically this command: less -isM.

You'll also need Ncurses for this build.
Create a Workspace
I recommend creating a workspace under your /home/<your user>/ directory that is dedicated to this build. So let's fire up your terminal and run the following:
Now that we have a workspace created and we are currently in the src directory we can begin bringing down the sources and extracting them.

Build Environment
To make things a little smoother let's setup some environment variables:
$ export INSTALLDIR=~/workbench/gcc-g++-4.8.2/arm $ export PATH=$INSTALLDIR/bin:$PATH $ export TARGETMACH=arm-none-linux-gnueabi $ export BUILDMACH=i686-pc-linux-gnu $ export CROSS=arm-none-linux-gnueabi $ export CC=${CROSS}-gcc $ export LD=${CROSS}-ld $ export AS=${CROSS}-as $ export CXX=${CROSS}-g++NOTE: Depending on whether you are using a cross-compiler built from my other wikis you might need to change INSTALLDIR to point to your cross-compiler.Build less
